template< class RealType, size_t bits, class Generator > RealType generate_canonical( Generator& g );		(since C++11)

Generates a random floating point number in range [0; 1).

g() is called as many times as needed to generate enough entropy, i.e. at least max(1, ⌈ min(b
1, b
2) / log
2 R ⌉) times, where

• b1 = std::numeric_limits<RealType>::digits
• b2 = std::numeric_limits<RealType>::bits
• R = g.max() - g.min() + 1.
